Hi, i have an lmc liberty 2001, the schaudt it992 control panel was working fine then suddenly will only read a max of 12.25v when pressing the switch to get a reading from both batteries. If i put a multimeter across both the batteries it reads 12.7v. The meter on the panel shows 13.2v on the leisure battery when charging from the mains and 12.5v on the engine battery, which shows 13.2v on the multimeter! The water tank gauges read fine as does the amp meter. Any ideas what is wrong or does anyone repair these panels. I understand they cost about £190! Many thanks. Brian.
